Still looking for a reliable source for the breakdown on more serious side effect by sex/and age
See our collections of data on Australia’s COVID-19 vaccination program.

There is a graph called "Doses by age and sex", and it seems at least in Australia the groups that initially had AZ, had a similar take uptake.
Although not peer-reviewed or scientific, middle-aged men reporting a greater willingness in Australia to take up AZ (the Guardian and possibly the SMH?) survey so potentially had a greater uptake of the AZ.
